DNA methyltransferase 3a (DNMT3a) is a de novo methyltransferase important to the epigenetic control of cell fate.

|
T cells lacking DNMT3a simultaneously express IFN-gamma and IL-4 after expansion under nonbiasing conditions.

|
While global methylation of DNA from wild-type and knockout T cells is similar, DNMT3a-null T cells demonstrate selective hypomethylation of both the Il4 and Ifng loci after activation.

Previous studies have shown that short-term (4 weeks) or chronic (32 weeks) exposure to trichloroethylene (TCE) in drinking water of female MRL+/+ mice generated CD4(+) T cells that secreted increased levels of interferon (IFN)-γ and expressed an activated (CD44(hi)CD62L(lo)) phenotype.

|
Also observed was an increase in the expression of Dnmt1 (DNA methyltransferase-1) and decreased expression of several genes known to be downregulated by DNA methylation, namely Ifng, Il2, and Cdkn1a.

|
CD4(+) T cells from a second study in which MRL+/+ mice were treated for 17 weeks with TCE showed a similar increase in Iap and decrease in Cdkn1a.

Firstly, epigenetic enzyme gene expression (histone deacetylase (HDAC) and DNA methyltransferase (DNMT)) was measured after LPS stimulation.

|
Results showed differential expression of HDAC6, HDAC7 and DNMT3A genes in response to LPS in cells from all animals, while TSA significantly inhibited pro-inflammatory cytokine (TNF, IL2 and IFNG) expression (P<0.05), presumably by histone acetylation.

Downregulation of IFNG in CD4(+) T cells in lung cancer through hypermethylation: a possible mechanism of tumor-induced immunosuppression.
|

|
Hypermethylation of the IFNG promoter in CD4(+) T cells and plasma IFNG was negatively correlated.
|
| 11 |
24244422
|
CD4(+) T cells from healthy individuals co-cultured with SPC-A1 cells generated lower levels of IFNG after activation, elevated expression of DNA methyltransferases (DNMTs), and exhibited hypermethylation of the IFNG promoter.
|
| 12 |
24244422
|
In conclusion, decreased IFNG expression of CD4(+) T cells co-cultured with lung cancer cell is associated with IFNG promoter hypermethylation.
|
| 13 |
24244422
|
Our study suggests that interaction between lung cancer cells and CD4(+) T cells induces DNMT expression and IFNG promoter hypermethylation in CD4(+) T cell, which may serve as an important mechanism of tumor-induced immunosuppression.
